While all the other original cast members of MTV's Teen Mom are moving on with their lives-- getting married, getting spin-off shows, getting back together with exes, etc. -- Amber Portwood is voluntarily serving out her five-year jail term in an Indiana penitentiary, instead of complying with the terms of her court-ordered drug program after violating her probation stemming from a December 2011 arrest for drug possession. And hey, it seems to be going well so far. You know how we can tell? She's lost 25 pounds!

Her mom, Tonya, reports that her first visit with her daughter "was emotional and filled with lots of hugs and tears, but she looks great and she's already done a complete 180 since being locked up. She's lost a lot of weight by staying active." Um. Good job!?

I'm not quite sure how I see one thing having ANYTHING to do with the other?! Any unremorseful drug addict with serious emotional and mental issues can "stay active," eat a regimented, non-junk diet (aka what Amber's likely eating, because she is IN JAIL), and slim down. Sure, it's a positive side effect of her being in prison, I suppose, but it's just incredible that her daughter's weight loss is what Tonya is touting. I mean, RLY?! How about hearing how she's gotten her act together mentally, emotionally, etc.?

Thankfully, she goes on to note ...

... even though the guards and inmates try to pick fights Amber is staying out of trouble and spending time each day writing a book about her life. Now instead of fighting and taking drugs, Amber is heavily into the jail choir and practices every day with them. She is loving it and hopes one day Leah will come and watch her perform.

Well, obviously, Tonya, your daughter can't cope by taking drugs, because, again, she is IN JAIL. But yes, these do sound like productive, significant, positive developments in Amber's life. So, let's focus more on this news and less on the completely trivial weight loss, please? Hearing that one of the most screwed-up Teen Mom stars is slimming down -- by being on a prison diet plan! -- isn't doing anyone any favors. Priorities, people!
